IMPROVEMENT IN VEHICLE-WHEEL HUBS.

Specification forming part of Letters Patent N 0. 202,315, dated April9, 1878 application filed March 20, 1878.

To all whom it may concern:

BeitknownthatLGARL THEonoRWEcKER, of Offenbach, Germany, have invented anew and useful Improvementin WheeLHubs, which invention is fully setforth in the following specification, reference being had to theaccompanying drawing, in which Figure 1 represents a longitudinalcentral section of my improved hub. Fig. 2 is a section on the line 00as, Fig. 1. Fig. 3 is a front view.

This invention consists in a hollow wheelhub having a circumferentialdepression, the opposite walls of which are connected by an annularseries of cross-bars at equal distances apart, forming sockets, and aninwardly-project-in g flange at each side of said depression, separatedfrom the wall thereof, and forming abutments for the ordinary elasticgaskets.

In the drawing, the letter S designates a hollow hub, which may be madeof any suitable material. Near the middle of this hub its wall isdepressed to form a circumferential chamber, A, which, by means ofwedgeshaped cross stays or bars N, is divided into a series ofspoke-sockets. From the bottom of this chamber rise wedge-shaped annularflanges a a, which penetrate and spread the inner ends of the spokes L,so that they will snugly fit against the walls of the socket-chamber,which widens toward the center of the hub, so as to hold the spokesfirmly. At each side of the socket-chamber, and projecting inwardly fromthe wall of the hollow hub, are flanges f g, which strengthen the huband form abutments or supports-for the ordinary elastic gasketsindicated by the letter H, and between said flanges and the walls of thesocket-chamber are vacant spaces or chambers, which impart lightness tothe hub. The axle-box is designated by G, and is held in position in thehub by a nut, K, and O is the nut which holds the axle F in the box inthe ordinary manner.

By means of the construction abox e described, it will be seen thatwhile my improved hub is strong and thoroughly braced it is very light,neat in form, and adapted for applicaiion' to any of the ordinary kindsof vehicles and axle-boxes.

What I claim is- The hollow wheel-hub, having the annular depressedsocket-chamber, the inwardly-extending, bracing, and gasket supportingflanges, and the open spaces or chambers between said flanges and thewalls of said chamber, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this26th day of January, 1878.

CARL THEODOR WEOKER.
